Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device, and more particularly to an image display device suitable for displaying a brain morphological image and a brain function image by a nuclear magnetic resonance signal or the like.

[0002]

2. Description of the Related Art In recent years, various techniques for measuring brain function without opening the head have been proposed, and are widely used in surgical planning of cerebral surgery, physiological fields, and the like. A typical one of these methods is a brain function MRI (Magnetic Resonance Imagin).
g), optical topography, PET (Positron Emission T)
omography), brain waves, brain waves, and the like.

[0003] In many cases, a brain function image is superimposed on a morphological image measured by MRI or the like in order to obtain anatomical position information of a brain function activation site. Usually, brain function measurement is often performed using any one of the methods, and a method of displaying a brain function image in color on a morphological image displayed in gray scale is the most common. In this method, the display color of the brain function image is assigned according to the magnitude of the activation, and a color bar is displayed to clarify the correspondence between the magnitude of the activation and the display color. Alternatively, it may be displayed in one color regardless of the magnitude of the activation.

Recently, there are many examples of simultaneous measurement of brain function using a plurality of measurement methods. For example, brain function MR
I and optical topography have an advantage and a disadvantage. Brain function MRI is capable of measuring the whole brain, has relatively high spatial resolution, and has the advantage of easy identification of brain function activation sites, but has low temporal resolution and the mechanism of signal change is unknown. There is a disadvantage that there is. On the other hand, optical topography has the disadvantage that the measurable area is limited to the vicinity of the surface of the brain, has low spatial resolution, and it is difficult to identify brain function activation sites. It has the advantage of being clear. Therefore, in order to compensate for the respective disadvantages, simultaneous measurement of brain function MRI and optical topography may be performed, but in the conventional image display method,
The images were displayed as separate images for each measurement method.

When obtaining a morphological image by MRI, an imaging method called T1 enhancement is often used. When this imaging method is used, an image in which the contrast between brain tissues is emphasized can be obtained, and thus the sulci can be easily identified. However, in order to obtain more specific anatomical information, an image obtained by another measurement method may be obtained. For example, it is important to know the running state of blood vessels and nerve fiber bundles in order to clarify the source of a signal obtained by brain function measurement. In order to measure a blood vessel image by MRI, a technique such as a phase contrast method is used.

[0006] Recently, studies have been made to image nerve fiber bundles by utilizing the large anisotropy of molecular diffusion in nerve fibers. Proc for imaging of nerve fiber bundles
eedings of the National Academy of Sciences
of the United States of America, Vol. 96, p
p.10422-10427 (1998) (hereinafter referred to as Reference A). In the above document A, a display example of a brain function MRI image and a nerve fiber bundle image is illustrated, and a brain function MRI image and a nerve fiber bundle image are superimposed and displayed on an MRI morphological image. Further, a region of interest is specified on the morphological image or the brain function MRI image after the threshold processing, and only the nerve fiber bundle in the region of interest is displayed. In the case of three-dimensional display, a projection viewed from two directions is displayed.

[0007]

In the prior art, since the brain function images simultaneously measured by a plurality of brain function measurement methods are displayed as separate images, the spatial relationship between the plurality of brain function measurement images can be understood. There was a first problem that it was difficult.

When a brain function image and a nerve fiber bundle image are superimposed on a morphological image and displayed, for example, in Document A, only a nerve fiber bundle associated with a desired brain function activation site is selectively displayed. For this purpose, an elliptical or rectangular area is specified on the morphological image or the brain function image, and only nerve fiber bundles sharing pixels with the above-mentioned area are extracted and displayed. However, it is difficult to reliably extract only a nerve fiber bundle associated with a desired brain function activation site by an area specification method using an ellipse or a rectangle. For this reason, the conventional technique as described in the above-mentioned Document A has a second problem that only nerve fiber bundles related to a desired activation site cannot be reliably extracted.

In the prior art, the nerve fiber bundle is
Although there is a means for selectively displaying a region, there is a third problem that a region for activating a brain function is not provided with a means for selectively displaying a region.

[0010]

In order to solve the above first problem, an image display apparatus according to the present invention provides a brain for selecting a desired brain function image from brain function images measured by a plurality of measurement methods. A function image display switching means is provided, and the brain function image and the nerve fiber bundle image selected by the switching means are displayed on the morphological image.

Similarly, in order to solve the first problem,
The image display device according to the present invention has main / sub display mode switching means for separating two or more types of brain function images into a main brain function image and a sub brain function image, and the main brain function image is displayed on the same morphological image. The functional image and the secondary brain function image are simultaneously displayed using different display methods. As a different display method, for the secondary brain function image, for example, only the outline of the brain function activation site is displayed.

According to the present invention, when there are two or more types of the secondary brain function images, the outline of the brain function activation site is displayed in a different color or line type, or the main brain function image is displayed. In the region where the secondary brain function image overlaps with the secondary brain function image, display according to the purpose is performed, such as displaying the main brain function image on the front side and simultaneously displaying two or more types of brain function images on the same morphological image at the same time. It is possible.

In order to solve the second problem, the image display device according to the present invention has a user interface for selecting a pixel, which is a continuous area including the pixel in the brain function image, and which is provided in advance. A region constituted by pixels having a pixel value exceeding the threshold value is selected as a brain function activation site, and only the nerve fiber bundle sharing the pixel with the brain function activation site is displayed on the morphological image. is there.

In order to solve the third problem, the image display apparatus according to the present invention has a user interface for selecting a nerve fiber bundle, and another brain function activation site sharing a pixel with the nerve fiber bundle. Is displayed on the morphological image.

The result of performing the extraction processing of the nerve fiber bundle to be performed may be used.

However, in recent years, there are various methods for measuring brain functions such as magnetoencephalography, PET, optical topography, etc., and all have advantages and disadvantages. Therefore, brain functions of the same subject are measured using a plurality of measurement methods. There are many cases.

In the nerve fiber bundle image display apparatus according to the present invention, the brain function image display switching means (the brain function image display switching means () is used to display the brain function image and the nerve fiber bundle image measured by different measurement methods on the morphological image. 104, 204, 30
5). In the example of FIG. 1, since the brain function image display switching unit 104 is set to a mode for displaying a brain function MRI image, the brain function MRI image 102 is displayed.

In the following embodiment, an example of an image display means for displaying a brain function image and a nerve fiber bundle image measured using a brain function measurement method other than MRI on a morphological image will be described. In FIG. 2, the brain function image display switching means 204 is set to the display mode of the optical topography image, and the optical topography image 202 and the nerve fiber bundle image 203 are changed to the morphological image 20.
1 is displayed above. Brain function image display switching means 204
By switching the display mode with, a brain function image measured using another measurement technique can be displayed.

The brain function image to be displayed when each display mode is designated is selected in advance by using the display image selecting means 1301 shown in FIG. For example, in the brain function MRI image selection unit 1302, the candidate image file name display unit 130
When a desired image file is selected from the brain function MRI images listed in 5, the selected image file name display unit 13
At 06, the desired file name is displayed. Optical topography image selection unit 1303 and PET image selection unit 13
At 04, a display image is selected in the same manner.

When the shape image and the brain function image are measured by the same measuring device, an image of the same cross section can be obtained. For example, a morphological image is obtained by MRI, and a brain function image is obtained by optical topography. In some cases, it is necessary to separately acquire information on the imaging section. Usually, a morphological image is acquired by attaching a marker indicating the position of the optical topography probe, and the position of the optical topography probe is identified from the position of the marker on the morphological image. In FIG. 13, a brain function MRI image selection unit 1302, an optical topography image selection unit 1303, and a PET image selection unit 1304
Although the example of the display image selecting unit 1301 having the above is shown, the type of the brain function image is not limited to the above example.

In the following embodiment, an example of an image display means for simultaneously displaying a plurality of brain function images measured using different measurement techniques on the same morphological image will be described. In FIG. 3, the brain function image display switching means 305 is set to a display mode of a brain function MRI image and an optical topography image,
A brain function MRI image 302 and an optical topography image 303 are displayed on the morphological image 301. The nerve fiber bundle image 304 may be further displayed on the same screen.

In a general brain function image, the magnitude of the brain activation is displayed by using the gray value, color, etc. of the image, so that the magnitude of the brain activation is displayed simultaneously for two or more types of brain function images. It is difficult. Therefore, in the present invention, two or more types of brain function images to be displayed simultaneously are classified into a main brain function image and a sub brain function image by using the main / sub display mode switching means 306 to 308, and different display methods are used. To display. For example, a main brain function image displays a signal change using a grayscale value, a color, or the like, and a sub brain function image displays only an outline portion of an activated part.

In FIG. 3, the main brain function image is an optical topography image 303, and the secondary brain function image is a brain function MR image.
Since the image is the I image 302, the brain function MRI image 302 displays only the outline portion. If there are two or more types of secondary brain function images, the outlines of the activated parts are displayed in different colors or line types.

FIG. 4 shows another example of simultaneously displaying a plurality of brain function images. In this example, the secondary brain function image also displays a signal change using grayscale values, colors, and the like. In a region where the main brain function image and the sub brain function image overlap, the main brain function image is displayed on the front. In the region where the main brain function image and the sub brain function image overlap, the outline of the activated part of the sub brain function image is displayed. Main / sub display mode switching means (306 to 308 in FIG. 3 or 40 in FIG. 4)
6 to 408), when the main brain function image is re-selected, the main brain image can be displayed again with the same combination of brain function images interchanged.

In the examples of FIGS. 3 and 4, the brain function image display switching means 305 and 405 also serve as the main / sub display mode switching means, and the optical topography is selected as the main brain function image. Instead of using different display methods as shown in FIGS. 3 and 4, a plurality of brain function images may be displayed translucently.

FIG. 5 shows a brain function image 50 on a morphological image 501.
2, an example in which a nerve fiber bundle image 503 and a blood vessel image 504 are displayed. The display order switching unit 505 switches the order in the depth direction of the screen displaying the brain function image 502, the nerve fiber bundle image 503, and the blood vessel image 504. In the example of FIG. 5, since the setting of the display switching means 505 is in the order of the blood vessel image, the nerve fiber bundle image, and the brain function image, the nerve fiber bundle image 503 is placed in front of the brain function image 502 and the blood vessel image. The image 504 is displayed on the foreground. By appropriately changing the setting of the display switching means 505, a desired image can be displayed on the foreground.

Usually, a plurality of activation sites are scattered in a brain MRI image, and the activation sites are rarely localized in one region as illustrated in the above example.
In addition, since nerve fibers are usually extracted based on the starting point selected by the user, the number of nerve fiber bundles depends on the number of starting points selected. However, depending on the type of brain activity, multiple nerve fiber bundles may be involved. Therefore, when all the activation sites and nerve fiber bundles are displayed at the same time, there is a danger of falling into an information overload situation. Therefore, in this embodiment,
